The U.S. is looking for successors to Saddam. One is Ahmed Chalabi--but some say he's yesterday's man

Compared with the gilded Baghdad palaces from which Saddam Hussein ruled Iraq, the bombed-out remains of an air-defense base a few miles outside the southern city of Nasiriyah don't look much like a headquarters for the country's next government. The only intact building is a dusty, flea-infested warehouse that had no windows, no running water, no bathrooms. But that is where Ahmed Chalabi, the controversial leader of the once exiled Iraqi National Congress (I.N.C.), set up shop last week after the Pentagon airlifted him and some 600 fighters of his newly named Free Iraqi Forces into the heart of liberated Iraq.
